Suggestion for no.1

Step 1: destroy air defense at blue circle with lightning spells
Step 2: deploy lava at red arrow ( maybe its cc troops will be lured out)
Step 3: deploy 2 dragons at 2 red X to kill the cc troops 
Step 4: deploy dragons gradually at green X
 
Use the rage spells at where there are lots of stuff or when its cc troops are out

Avoid area of 2 gray circles (range of air defences)
Hold the king and queen in case we need them to make 50%

Suggestion on approach to take no.7 (for hall9)

Troops: mass dragons + king queen, 3 lightning spells + 1 rage spell

Step 1: lightning spells on air defense (yellow circle )
Step 2: king + queen at black arrow to destroy the air defense
Step 3: 2 dragons at orange circles (1 each)
Step 4: a line of dragons as brown straight line
Step 5: when air defense in pink circle starts to fire at dragons, deploy balloons at white arrow
Step 6: rage spell at purple circle as dragons approach

Suggestion for attacking method

This attack would use GoWi or GoWiWi or GoWiPe combo:

Notes: Never deploy 3 Golem as in red arrows, 90% fail.

Suggestion:

Step 1: use 2 giants at brown circle to lure the CC troops out, then lure to corner and kill them.
Step 2: deploy 2 golem at places of 2 blue arrows at 2 sides, when golem are fired, drop wallbreakers at 2 yellow arrows there to destroy the walls and open way for Golem.
Step 3: When 2 Golems enter at two sides, deploy the last Golem at the central blue arrow, together with wallbreakers at 3 remaining yellow arrows.
Step 4: When Golems go further inside, use jump spells at orange circle to help them jump inside.
Step 5: Deploy wizards follow the green crescent, yet concentrate on the 3 yellow arrows.

3 other spells: 2 rage spells and 1 healing spells, drop when you think it is necessary, usually when troops are close to townhall.

Troops: 3 Golems - 10 wallbreakers - rest are wizards + King & Queen

Killing castle troops

General method:

Normally, always bear in your mind that CC troops = CC attack ~> Corner and Circle

Specific approaches:

CC troops with low hit-points (equal or less than damage of 1 lightning spell), such as barchers, wizards, we can simply lure them all out to one place, drop 1 lightning spell right on them. This approach is often used for hall6 and below since it helps save your troops)

Valkyrie: lure it out to corner, then make a line of 20-25 archers, behind and in front of it. Note: never deploy your troops close to the Valkyrie or use barbs to kill Valkyrie because Valkyrie attacks the whole circle of troops surround it. Alternatively, if you are hall7 and above, using minions is the effective way to kill Valkyrie

Balloons: similar to dealing with Valkyrie, deploy archers/wizards a bit far from balloons because balloons will kill all troops stand right below them, even when they explode. Alternatively, if you are hall7 and above, using minions is the effective way to kill Balloons

Dragons/Wizards: make of circle of archers/wizards/minions (around 25 archers) around the dragon after luring it to corner, it will be killed rapidly. Never deploy your troops at 1 place because dragons and wizards have slash damage which means they will kill all at once all troops who stand close to each other.

Witch: 1 lightning spells right at it (for hall6 and below). Hall7 and above, you can use barchers, minions, wizards, or dragons.

Luring castle troops

We may not win if the base is so tough but Nike Crew will not lose just simply because our troops are killed by their castle troops.
